Hey Jason what do you think about stringing the wilson 99s with Solinco outlast 16s? The outlasts are known for holding tension very well as well as durability. How long do you think it'll last on a 16x15 string pattern?

I haven't tried the outlast in quite some time, but I think it would be a great fit. Little bit stiffer and it holds tension well. Even stiffer strings feel softer in the 16x15 string pattern. As far as how long it lasts, it really depends. Too many factors like how hard you hit the ball, how many hours you play, the tension you use. Tough thing with using polys, especially in the Steam 99S or 105S, is that they lose tension quickly. If it were up to me, I'd probably cut it out in about 3 weeks, 4 weeks max.
